Description

Technical Field

[0001] This invention relates to an edge trimming machine, and more particularly to an edge trimming machine used in decoration, construction and other applications. Background Technology

[0002] A trimming machine is a power tool that uses a motor assembly to drive a cutting head to process wood and other workpieces. It typically consists of a main body housing the motor assembly, a cutting head detachably mounted to the main body and driven by the motor assembly, and a base that axially slides and supports the main body. The rotation of the motor assembly causes the cutting head to rotate, thereby performing grooving or chamfering on the workpiece. Furthermore, the axial relative position of the main body to the base can be adjusted to change the cutting depth, meeting the operator's needs for grooving to different depths.

[0003] To achieve the adjustment and fixation of the main body relative to the base, a position adjustment and fixing mechanism is usually used. However, traditional mechanisms place the adjustment mechanism for adjusting the relative position and the fixing mechanism for fixing the relative position at different positions on the base, which is cumbersome to operate and also makes the base larger, which does not meet the requirements of miniaturization.

[0004] For improvements to the above structure, please refer to Chinese Invention Patent No. CN202053317U, published on November 30, 2011, which discloses a trimming machine including a motor unit and a base. The base supports the motor unit and is configured to place the motor unit on the workpiece. The base has a clamping cylindrical portion and an adjustment and fixing mechanism disposed on the clamping cylindrical portion. The adjustment and fixing mechanism has a support shaft component, a pinion gear as a rotating component, and a cam rod component. The support shaft component and the pinion gear serve to adjust the relative position of the motor unit relative to the base. The adjustment mechanism functions as follows: the support shaft assembly and the cam rod assembly serve as a mechanism for fixing the relative position of the motor unit relative to the base. The support shaft assembly, being a shared component of both the relative position adjustment and fixing mechanisms, reduces the number of parts and allows for a smaller overall base. However, when adjusting the position of the cutter head mounted on the spindle relative to the workpiece, the operator must first adjust the support shaft assembly, then simultaneously tighten the support shaft assembly and rotate the cam rod assembly to the closed position. This requires both hands to work together, and the operator must hold the trimmer suspended in the air to complete the tightening and rotation, resulting in a high level of operational difficulty. Therefore, this adjustment and fixing mechanism fails to meet the requirements for convenient adjustment and does not conform to the concept of human-machine interface.

[0005] Therefore, it is indeed necessary to provide an improved trimming machine to overcome the shortcomings of the existing technology. Summary of the Invention

[0029] Please see Figure 1 and Figure 2 As shown, an embodiment of the present invention relates to a trimming machine 100, which is used for grooving or chamfering the edges of processed parts such as wood. The trimming machine 100 includes a main body 101 and a base 103 supporting the main body 101. The main body 101 is slidably disposed relative to the base 103. Adjusting the relative position of the main body 101 with respect to the base 103 adjusts the cutting depth of the trimming machine 100. A battery pack 104 is connected to the upper end of the main body 101, and a cutting head 102 is mounted on its lower end, protruding from the lower end of the base 103.

[0030] The battery pack 104 provides power to the main body 101, which drives the cutter head 102 to rotate. When the operator is working, the end face of the base 103 is brought into contact with the workpiece, and the trimmer 100 is moved along the required trajectory to trim the workpiece.

[0031] Combination Figure 3As shown, the main body 101 includes a housing 1 formed on the periphery of the main body 101, a motor assembly 2 installed inside the housing 1, a fan 4 connected to the motor assembly 2, a chuck 3 fixed to the end of the motor assembly 2 for clamping the cutter head 102, and a control assembly 5 electrically connected to the motor assembly 2. The control assembly 5 can control the start, stop, and speed of the motor assembly 2. The fan 4 is used to dissipate heat from the motor assembly 2 and the control assembly 5 to prevent the trimming machine 100 from shutting down due to overheating protection.

[0032] Furthermore, the fan 4 and the chuck 3 are located at the lower end relative to the motor assembly 2, and the control assembly 5 and the battery pack 104 are located at the upper end relative to the motor assembly 2. Inside the trimmer 100, the chuck 3, fan 4, motor assembly 2, control assembly 5, and battery pack 104 are arranged in sequence from bottom to top.

[0033] Specifically, the motor assembly 2 includes a main shaft 24 extending generally vertically, with at least a portion of the main shaft 24 protruding outside the housing 1. The end of the main shaft 24 has external threads for detachably securing the chuck 3, and the cutter head 102 is connected via the chuck 3 to the protruding end of the main shaft 24 at its axially lower end within the housing 1. When operating the trimmer 100, the battery pack 104 is first switched on to provide power, and then the motor assembly 2 is activated via the control assembly 5. The motor assembly 2 drives the main shaft 24 to rotate, which in turn rotates the cutter head 102 to perform grinding and polishing operations.

[0034] In this embodiment, the aforementioned housing 1 includes a cylindrical inner housing 12, a bearing positioning sleeve 14 mounted on the upper end of the inner housing 12, a controller housing 13 housing the control assembly 5, and an outer housing 11 sleeved around the outer periphery of the inner housing 12. The outer housing 11 and the bearing positioning sleeve 14 are both metal housings 1, ensuring machining and rotational accuracy; while the inner housing 12 and the controller housing 13 are made of resin material to meet the insulation requirements between electronic components. Specifically, the outer housing 11 holds the inner housing 12, meaning the cylinder of the outer housing 11 partially overlaps with the inner housing 12 along the axis of the main shaft 24, covering the outer periphery of the inner housing 12. Simultaneously, the upper end of the outer housing 11 holds the bearing positioning sleeve 14 and part of the controller housing 13.

[0035] The inner housing 12 houses the motor assembly 2. Since the inner housing 12 is made of insulating material, it has excellent insulation properties and can prevent electrical conduction. Furthermore, the outer housing 11 is slidably connected to the base 103. The metal outer housing 11 can evenly bind the outer circumferential surface of the housing 1, improving the dimensional accuracy of the outer circumferential surface of the housing 1 supported by the base 103 and preventing dimensional changes in the outer circumferential surface that would make it difficult for the main body 101 to slide. Simultaneously, a rack 111 in the axial direction is provided on the outer circumferential surface of the outer housing 11, and a display scale for indicating the relative position of the main body 101 relative to the base 103 is provided on the lateral side adjacent to the rack 111.

[0036] In this embodiment, the motor assembly 2 includes a stator 22, a rotor 21 sleeved within the stator 22, a main shaft 24, and bearings 23 supported at both axial ends of the main shaft 24. The bearings 23 support the main shaft 24 to improve the rotational accuracy of the main body 101.

[0037] Please refer to the following: Figure 1 and Figure 2 As shown, the base 103 includes a seat 6 that holds the main body 101, a base plate 7 that abuts against the workpiece, and an adjustment assembly 8 installed on the seat 6. Operating the adjustment assembly 8 can cause the seat 6 to hold the main body 101 or the seat 6 to separate from the main body 101.

[0038] Combination Figure 4 As shown, the aforementioned base 6 has a generally C-shaped cylindrical portion 61, a groove 62 formed in the cylindrical portion 61, lugs 63 protruding outward from the outer periphery of both ends of the cylindrical portion 61, a support hole penetrating the lugs 63, a window portion 65 located below the lugs, and a through hole 66. The cutting head 102 protrudes from the hole 66 onto the lower surface of the base plate 7.

[0039] Specifically, the groove 62 is located on the front side of the cylindrical portion 61, making the cylindrical portion 61 C-shaped when viewed from above. The distance between the inner circumferential surfaces of the cylindrical portion 61 is increased or decreased by widening or decreasing the width of the groove 62. That is, when the distance between the inner circumferential surfaces of the cylindrical portion 61 decreases, this contraction is used to clamp the outer shell 11 of the main body 101. Conversely, when the distance between the inner circumferential surfaces of the cylindrical portion 61 increases, the outer shell 11 of the main body 101 is relaxed, allowing the main body 101 to slide up and down relative to the base 103. Furthermore, the window portion 65 is formed so that the hole 66 for protruding the blade 102 downwards can be seen, and the display scale can be observed for easy adjustment.

[0040] In this embodiment, the adjustment component 8 has the following three functions: it functions as an adjustment mechanism for adjusting the relative position of the main body 101 relative to the base 103; it functions as a fixing mechanism for locking the main body 101 so that it cannot move; and it functions as a limiting mechanism for restricting the sliding of the main body 101. The adjustment component 8 is configured in one location and has mutually interchangeable parts, that is, the fixing mechanism, the adjustment mechanism and the limiting mechanism have mutually interchangeable parts, so as to reduce the number of parts and make the base as a whole smaller.

[0041] Furthermore, the limiting mechanism engages with the adjusting mechanism to restrict the rotation of the adjusting mechanism.

[0042] Combination Figure 5 As shown, the aforementioned adjustment assembly 8 includes a support shaft component 81 mounted at a support hole on the base 6, and a rotating component 82, a cam rod component 83, and a snap-fit ​​component 84 connected to the support shaft component 81. The cam rod component 83 and the snap-fit ​​component 84 are located at both ends of the support shaft component 81. The support shaft component 81 and the rotating component 82 constitute an adjustment mechanism; the support shaft component 81 and the cam rod component 83 constitute a fixing mechanism; and the support shaft component 81 and the snap-fit ​​component 84 constitute a limiting mechanism. Therefore, the support shaft component 81 is the common component for the fixing mechanism, the adjustment mechanism, and the limiting mechanism.

[0043] Specifically, when adjusting the position of the main body 101 relative to the base 103, the cam rod component 83 must first be turned counterclockwise to release the locking mechanism from the main body 101. Then, the latch component 84 is pressed to release the limiting mechanism from the adjusting mechanism. Simultaneously, the support shaft component 81 is rotated to drive the rotating component 82, adjusting the relative position of the main body 101 relative to the base 103. Afterward, the latch component 84 is released, and the limiting mechanism restricts the unidirectional rotation of the support shaft component 81 and the rotating component 82. Finally, the cam rod component 83 is turned clockwise to lock the main body 101. During operation, pressing the latch component 84 requires rotating the rotating component 82. Although this requires the cooperation of both hands, it is convenient to use the hand holding the trimmer 100 with its hand suspended to press the latch component 84. The other hand can rotate the support shaft component 81 to drive the rotating component 82 to rotate, simultaneously completing the pressing and rotating operations. The operation is simple and convenient.

[0044] Combination Figure 6 As shown, the support shaft component 81 passes through the support hole and at least partially protrudes from both sides of the two lugs 63. The support shaft component 81 has a shaft body 811 installed in the support hole of the base 6, a ratchet portion 812 and an operating portion 813 provided on one side of the shaft body 811, a connecting portion 814 provided on the other side of the shaft body 811, and a handle portion 815 located between the ratchet portion 812 and the connecting portion 814. The operating portion 813, the ratchet portion 812, the handle portion 815 and the connecting portion 814 are arranged in sequence.

[0045] In this embodiment, the rotating component 82 is fixed to the support shaft component 81 and connected to the main body 101. The support shaft component 81 drives the rotating component 82 to rotate, causing the main body 101 to slide up and down along the seat 6. Preferably, the rotating component 82 is a pinion gear, which is fixed to the shank 815 and meshes with the rack 111. Rotating the operating part 813 causes the support shaft component 81 to rotate, the pinion gear rotates, and the rotating pinion gear rolls on the rack 111, so that the relative position of the main body 101 with the rack 111 relative to the base 103 changes up and down according to the arrangement direction of the rack 111.

[0046] In this embodiment, the cam rod component 83 acts on the seat 6 to lock / release the main body 101. The cam rod component 83 has a rotating shaft 832 mounted on the connecting part 814 and a cam rod body 831 connected to the rotating shaft 832. The cam rod body 831 rotates about the rotating shaft 832, causing the cam surface to abut / move away from the lug 63, thereby reducing / expanding the width of the groove 62.

[0047] Combination Figure 7 As shown, one end of the latching component 84 is movably connected to the outer peripheral surface of the seat body 6, and the other end is latched to the support shaft component 81 to restrict the unidirectional rotation of the support shaft component 81. The latching component 84 has a latching member 841 located between the seat body 6 and the support shaft component 81, a rib 844 protruding from the latching member 841 toward the support shaft component 81, a first positioning member 842 protruding from the latching member 841 away from the support shaft component 81, and an elastic member 843 mounted on the first positioning member 842. The rib 844 is engaged with the ratchet portion 812, and the first positioning member 842 abuts against the seat body 6 via the elastic member 843. Press the upper end of the buckle 841 toward the seat 6 to compress the elastic element 843, so that the rib 844 disengages from the ratchet part 812, and the support shaft part 81 can rotate freely; release the buckle 841, the rib 844 engages with the ratchet part 812, the support shaft part 81 cannot rotate in one direction, so that the main body 101 cannot slide downward due to its own weight.

[0048] This invention provides an adjustment mechanism and a limiting mechanism on the base 103, with the limiting mechanism engaging with the adjustment mechanism to restrict its rotation and thus limit the downward movement of the main body 101. Simultaneously, the adjustment mechanism and the limiting mechanism are mounted on the base 6 with shared components, reducing the number of parts and miniaturizing the overall base. Furthermore, adjusting the relative position of the main body 101 with respect to the base 103 requires only pressing the latching component 84 and rotating the support shaft component 81, resulting in low difficulty and ease of operation.

[0049] This invention is not limited to the specific embodiments described above.
